+By default you should not need to change / set the brightness setting as the default value (16) is sufficent for most purposes. Brightness can be changed by calling `setPanelBrightness(XX)` and then `clearScreen()`.
 
 The value to pass 'setPanelBrightness' must be a value less than MATRIX_WIDTH. For example for a single 64x32 LED Matrix Module, a value less than 64. However, if you set the brightness too high, you may experience ghosting.

-Summary: setPanelBrightness(xx) value can be any number from 0 (display off) to MATRIX_WIDTH-1. So if you are chaining multiple 64x32 panels, then this value may actually be > 64 (or you will have a dim display).
